- The Structure Repair Masque is a gentle treatment for damaged, dry and chemically treated hair that softens, moisturises and fights static electricity. Repairing Algae extract helps hair regain its natural strength, softness and shine. Colour Guard Complex protects and maintains the colour in colour treated hair. How to use: Apply to newly washed, damp hair. Leave in for 3 minutes. For a deeper acting effect, apply to towel dried hair and leave in for 5–10 minutes. Rinse thoroughly and finish treatment with the Structure Repair conditioner. Structure Repair uses strengthening ingredients from the sea in the form of algae that soften and repair damaged and tired hair. The Structure Repair-series has a fresh scent of vanilla, rose and jasmine. In comparison to our True Soft range, the Structure Repair series is tailored for damaged and chemically treated hair, while True Soft is suitable for naturally dry hair.
